Gungi was a male Wookiee Jedi Padawan who trained to become a Jedi in the Jedi Order during the era of the Galactic Republic. During the Clone Wars, Gungi and a group of five other younglings, Petro, Katooni, Byph, Ganodi, and Zatt, were deemed to be at the top of their class and, led by Ahsoka Tano and Jedi Grand Master Yoda, they traveled to Ilum to participate in the Gathering; an ancient Jedi ritual that proved a youngling‘s readiness to become a Padawan. Gungi managed to survive the Great Jedi Purge and continued acting as a Jedi during the early reign of the Galactic Empire.

Gungi, who was among the top of his class, was sent to Ilum with five of his fellow Jedi younglings. While on Ilum, the younglings were instructed by Jedi Master Yoda to enter a Crystal Cave and find their kyber crystals, which were necessary for the younglings to construct their first lightsabers. Every crystal in the cave was specific to each individual. Gungi found his crystal on an island across a body of water within the cave. Following Ganodi‘s advice not go into the freezing water, he meditated to wait for the body of water to freeze so he could cross. He was later commended by Master Yoda on his patience.
